China Sustainable Development Science Satellite No. 1 data is open and shared globally

On November 5, 2021, the Sustainable Development Science Satellite 1 (SDGSAT-1) was successfully launched at the Taiyuan Satellite Launch Center in China. The satellite is the world's first scientific satellite dedicated to serving the United Nations' 2030 Agenda for Sustainable Development. .

According to a report by China News Network yesterday, on the 20th local time, Chinese State Councilor and Foreign Minister Wang Yi announced at the ministerial meeting of the "Group of Friends of the Global Development Initiative" in New York that China's "Scientific Satellite 1 for Sustainable Development" launched last November. Data is open and shared globally , helping countries in sustainable development research and decision-making.

According to reports, the Sustainable Development Science Satellite 1 aims to detect land, ocean and other surface parameters closely related to human activities, and can finely monitor the interaction between human activities and the natural environment. Yesterday, the satellite's open science plan service system was officially launched, accepting data and research applications from researchers worldwide and providing scientific data for domestic and foreign scientists engaged in sustainable development research.

On December 20, 2021, the first batch of images of the Sustainable Development Science Satellite 1 was officially released, including China's Yangtze River Delta, Shandong Peninsula, Tibet Namco, Xinjiang Aksu, Beijing, Shanghai and Paris, France, etc. Low-light, multispectral and thermal imager images of regions and cities.

Among them, the low-light imager reflects social and economic development and the pattern of human settlements by detecting the intensity and distribution of lights at night. Multi-spectral data has the characteristics of large width and high signal-to-noise ratio, and its band setting is suitable for monitoring the water color index, transparency, and suspended matter of various turbid water bodies. Thermal infrared imagers can finely detect land surface and water surface temperature, fine water and heat dynamic changes in farmland, urban thermal energy distribution, etc., and provide basic data for crop growth, disease, and insect pest occurrence environment, energy consumption, and surface temperature changes.
